KIEV, Ukraine – Ukraine's prime minister says his country is "still in a state of war" with neighboring Russia despite a cease-fire between the government forces and Moscow-backed rebels in the east.

During a Saturday conference with politicians and business leaders in Kiev, Arseniy Yatsenyuk said Russian President Vladimir Putin "wants to restore the Soviet Union" and destroy Ukraine.

The statement came as a Russian convoy of trucks filled with humanitarian aid crossed the border into war-torn east Ukraine.

Rayan Farukshin, a spokesman for Russian customs, told the Associated Press by phone that the last truck crossed onto Ukrainian soil early Saturday. He could not confirm the number of trucks, but news agency ITAR TASS reported that there were about 200.
